My current gaming PC is about 11 years old and uses a GTX 980 Ti. It has served me well, but newer games such as Battlefield 6 now require TPM 2.0, which my platform does not support. I mainly play multiplayer shooters including Battlefield, Hunt: Showdown, Rainbow Six, and GTA Online, and I would like to be ready for GTA 6 eventually. My display is 1440p at 144 Hz, and I have no interest in moving to 4K.
I would prefer to spend around €700, with €2,000 as an absolute maximum if necessary. Since I do not game as much as I used to, I would like to reuse as many parts as practical for both environmental and financial reasons. I assume the hard drives can stay, and I am wondering whether my existing DDR4 memory is compatible with a newer system or whether its speed would make it a poor choice. I would also like to keep the case if possible.
I have seen people use an older graphics card specifically for Lossless Scaling while a newer GPU renders the game. Could keeping my GTX 980 Ti as a secondary card be useful, or would it be better to sell it and put the money toward a new build?

The main limitation is not just the graphics card—it is the entire older platform. Your CPU is likely to bottleneck a modern GPU, especially in CPU-heavy multiplayer games, so a worthwhile upgrade should include a newer processor, motherboard, and cooler. The existing SSD and possibly the power supply may be reusable if they are in good condition and have suitable connectors, but the 980 Ti and slow RAM are better treated as items to sell.
€700 may be tight for a balanced 1440p system in the current market. Increasing the budget to roughly €900–€1,000 would make it easier to choose a modern midrange GPU that can handle 1440p properly. Keeping the case and storage could help reduce the total.
You could technically reuse the 32 GB of DDR4, but its low speed would hold back a newer CPU enough that I would not build around it unless the budget absolutely required it. A newer DDR4 platform could be cheaper than DDR5, while a current DDR5 platform offers a better upgrade path. For example, an entry-level modern AMD system could start with 16 GB of DDR5 and add another matching module later, although running two sticks from the beginning is preferable.
The GTX 980 Ti may still manage older or less demanding games at 1080p with upscaling, but it is inefficient and underpowered for a modern 1440p build. Reusing the case, SSD, and perhaps the PSU is more practical than keeping the graphics card as a dedicated scaling device.
A second GPU probably is not worth keeping for Lossless Scaling. Newer graphics cards generally have better built-in upscaling and frame-generation options, and in cases where Lossless Scaling is useful, a modern system should usually have enough performance headroom to run it on the main card. Adding the 980 Ti could also restrict airflow, use more power, and create driver or compatibility complications. Selling it would be a better way to give it another use while adding a little to your upgrade budget.
Your DDR4 can technically work in some newer DDR4 systems, but 2133 MHz is quite slow by current standards. Around 3200 MHz is more typical, so reusing the old memory may noticeably reduce CPU performance. The case can usually be reused as long as it supports the new motherboard and graphics card, though it may lack conveniences such as front-panel USB-C.
Thanks for the detailed explanation. I had not considered the airflow and power drawbacks of keeping the second card installed.

That makes sense. I was hoping the old platform could stretch further, but it sounds like replacing the core components together is the more sensible approach.
